Abstract:
Objective? The Chinese version of the Violence Risk Screening-10 (V-RISK-10) was tested for its reliability and validity in evaluating people with schizophrenia in community, so as to examine its predictive effect on the occurrence of aggressive behaviors. Methods? A systematic random sampling method was used to select 385 schizophrenics from 22 streets in Zhanjiang city as subjects. In June 2018, the Chinese version of V-RISK-10 questionnaire was used to predict the risk of violence, and a total of 380 cases were completed. Among them, 45 patients were retested on the Chinese version of V-RISK-10 after 2 weeks. From July to December 2018, the Ministry of Health's risk assessment method was used to track and observe the occurrence of patient attacks. There were 6 sessions of the evaluation, once a month, and 379 patient attacks were followed. Results? The Chinese version of V-RISK-10 Cronbach's alpha coefficient was 0.729 (P＜0.001). The Pearson correlation coefficient of the total score of the retest reliability scale was 0.721 (P＜ 0.001). The Chi-square test showed that, there was a linear relationship between the Chinese version of V-RISK-10 assessment results and the actual incidence of aggressive attacks(χ2=26.743,P＜ 0.001). It was 0.267 of Kappa coefficient for consistency test, there was statistical significance(P＜ 0.001). The incidence of aggressive behavior was 15.57%. Taking the occurrence of aggressive behavior as the outcome variable, the area under the ROC curve of Chinese version of V-RISK-10 was 0.760 (95%CI: 0.694-0.825), and the sensitivity and specificity were 81.36% and 57.19%, respectively. The corresponding positive predictive value and negative predictive value were 25.95% and 92.33%, respectively. The incidence of severe aggression in patients was 2.64%. Taking the occurrence of severe aggression as the outcome variable, the area under the ROC curve of Chinese version V-RISK-10 was 0.799 (95%CI: 0.651-0.947). The sensitivity and specificity of the tool were 60.00% and 87.80%, respectively. Conclusions? The Chinese version of V-RISK-10 has good reliability and validity in evaluating patients with schizophrenia in community, and has a good prediction effect on the occurrence of aggressive behaviors. It can be used as an aggressive behavior screening tool for patients with schizophrenia, and it is suitable for the community care workers to utilize.
